Description

Technical Field

[0001] This utility model relates to the field of anti-winding technology for steel wire ropes, and in particular to a double-chain balanced mechanical anti-winding device for steel wire ropes. Background Technology

[0002] Anti-winding is mainly used in cranes, grab equipment (such as four-rope grabs and multi-rope grabs), port loading and unloading, and mining operations to solve the problem of multiple wire ropes getting tangled due to uneven force or dynamic swing.

[0003] In the prior art, such as Chinese Patent Publication No. CN213865027U, a wire rope anti-tangling device is disclosed, belonging to the field of construction tools. Its technical solution includes: an adjustable-length support member and two clamping members disposed at both ends of the support member; the support member includes an outer sleeve with one end open and the other closed, and an inner rod inserted into the outer sleeve at one end, with a spring inside the outer sleeve capable of pushing the inner rod to move; the clamping members include a pair of clamps and a clamping screw, the clamping screw passing through the side wall of the clamp and threadedly connected to the clamp, with a wire rope passing through the clamp and clamped by the clamping screw. The beneficial effects of this utility model are: simple operation; when applied to hoisting operations, the two wire ropes will not tangle together, allowing workers to directly bind materials, thereby reducing labor intensity and improving production efficiency. Simultaneously, the adjustable length of the support member makes this device applicable to various construction situations.

[0004] The length of the support component in this patent is adjustable. However, in high-temperature environments, the spring may become less elastic due to thermal expansion, which reduces the resistance to the movement of the inner rod and shortens the length of the support component. In low-temperature environments, the spring may become harder due to cold contraction, which increases the resistance to the movement of the inner rod and may even cause the adjustment to fail, affecting the stability of the anti-winding device. Utility Model Content

[0005] The purpose of this invention is to solve the problems that in high-temperature environments, the spring may weaken due to thermal expansion, resulting in reduced resistance to the movement of the inner rod and a shortened length of the support; in low-temperature environments, the spring may harden due to cold contraction, increasing the resistance to the movement of the inner rod and even causing adjustment failure, thus affecting the stability of the anti-winding device.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: It includes a wire rope body, the surface of which is provided with an anti-winding component. The anti-winding component includes a fixing frame, a throttle inserted into the top of the fixing frame, a first gear connected to the bottom of the throttle, a second gear connected to the bottom surface of the first gear, a bidirectional screw threaded through the interior of the second gear, bearing sleeves fitted onto both sides of the bidirectional screw near the throttle, telescopic rods connected to the interior of both sides of the fixing frame, telescopic rods connected to the upper and lower ends of the telescopic rods, threaded holes opened inside the telescopic rods, a buffer component connected to the outer side of the telescopic rods, and a chain body connected to the outer side of the buffer component.

[0007] Furthermore, the throttle and the first gear are fixedly connected, and the position and size of the first gear match the position and size of the second gear.

[0008] Furthermore, the second gear and the first gear are meshed together, and the bidirectional screw and the bearing sleeve are rotatably connected.

[0009] Furthermore, the bidirectional screw is connected to the telescopic rod via a threaded hole, and the inner wall of the fixing frame is provided with a groove that matches the slider.

[0010] Furthermore, the outer surface of the slider is in contact with the inner wall of the groove, and a sliding connection is formed between the slider and the groove.

[0011] Furthermore, the main body of the chain is a G80 grade alloy steel lifting chain, and the main material of the bidirectional screw is high alloy special steel.

[0012] Furthermore, the buffer assembly includes a connecting block, the interior of which is connected to a spring, and the outer surface of which is connected to a top block.

[0013] Furthermore, a top rod is connected to the outer surface of the top block, and a side lug is connected to the surface of the connecting block near the telescopic rod.

[0014] Furthermore, a slot is formed through the interior of the side ear, a bolt is inserted into the slot, and a threaded groove is formed on the surface of the telescopic rod near the slot.

[0015] Furthermore, the bolt passes through the slot and forms a threaded connection with the threaded groove, the outer surface of the top block is in contact with the inner wall of the connecting block, and the top block and the spring form an elastic structure.

[0016] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, when it is necessary to adjust the length of the fixed frame, the throttle can be rotated to move the two sets of telescopic rods to both sides simultaneously through the screw rotation, and drive the two sets of chain bodies to expand outwards at the same time. The rigid structure of the chain body can suppress the lateral swing of the wire rope, avoiding the problem that the stability of the anti-winding device will be affected by the traditional adjustment method in high temperature environment.

[0017] 2. In this utility model, while in use, the two sets of springs can act as shock absorbers and buffers. During tower crane hoisting, the main body of the wire rope will generate instantaneous impact force due to material lifting, movement, or sudden braking. The springs absorb this energy through elastic deformation, preventing the impact force from being directly transmitted to the fixed frame and telescopic rod, thereby preventing structural damage due to stress concentration.

Detailed Implementation

[0020] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0021] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0022] Example 1, such as Figure 1 - Figure 5 As shown, this utility model provides a double-chain balanced mechanical anti-winding device for steel wire rope, including a steel wire rope body 1. An anti-winding component 2 is provided on the surface of the steel wire rope body 1. The anti-winding component 2 includes a fixing frame 201. A handle 202 is inserted into the top of the fixing frame 201. A first gear 203 is connected to the bottom of the handle 202. A second gear 204 is connected to the bottom surface of the first gear 203. A bidirectional screw 205 is connected through the interior of the second gear 204. Bearing sleeves 206 are fitted onto both sides of the bidirectional screw 205 near the handle 202. Telescopic rods 207 are connected to both sides of the fixing frame 201. Telescopic rods 207 are connected to both the upper and lower ends of the telescopic rods 207. Threaded holes 2 are formed inside the telescopic rods 207. 09. A buffer assembly 3 is connected to the outer side of the telescopic rod 207, and a chain body 210 is connected to the outer side of the buffer assembly 3. The throttle 202 is fixedly connected to the first gear 203. The position and size of the first gear 203 match the position and size of the second gear 204. The second gear 204 and the first gear 203 are meshed. The bidirectional screw 205 is rotatably connected to the bearing sleeve 206. The bidirectional screw 205 is threadedly connected to the telescopic rod 207 through the threaded hole 209. The inner wall of the fixing frame 201 is provided with a sliding groove that matches the slider 208. The outer surface of the slider 208 is in contact with the inner wall of the sliding groove. The slider 208 and the sliding groove are slidably connected. The chain body 210 is a G80 grade alloy steel lifting chain. The main material of the bidirectional screw 205 is high alloy special steel.

[0023] The effect achieved by the entire embodiment 1 is that when it is necessary to adjust the overall width of the anti-winding component 2, the reverse throttle 202 can be used to drive the first gear 203 to reverse. When the first gear 203 reverses, it will also mesh with the second gear 204 in the opposite direction, thereby driving the bidirectional screw 205 to reverse through the reverse meshing connection. When the bidirectional screw 205 flips, it will also rotate in the opposite direction with the telescopic rod 207 through the threaded hole 209. In turn, the two sets of telescopic rods 207 will move to both sides at the same time through the reverse thread rotation. When the appropriate width is adjusted, the throttle 202 can be stopped. When it is necessary to reduce the width of the anti-winding component 2, the forward throttle 202 can drive the bidirectional screw 205 to rotate forward, thereby driving the two sets of telescopic rods 207 to retract inward at the same time through the forward thread rotation. The rigid structure of the chain body 210 can suppress the lateral swing of the wire rope body 1, avoiding the problem that the stability of the anti-winding device will be affected by the traditional adjustment method in the high temperature environment.

[0024] Example 2, as Figure 1 and Figure 5 As shown, the buffer assembly 3 includes a connecting block 301, a spring 302 connected inside the connecting block 301, a top block 303 connected to the outer surface of the spring 302, a top rod 304 connected to the outer surface of the top block 303, a side lug 305 connected to the surface of the connecting block 301 near the telescopic rod 207, a slot 306 penetrating through the side lug 305, a bolt 307 inserted into the slot 306, a threaded groove on the surface of the telescopic rod 207 near the slot 306, and a threaded connection between the bolt 307 and the threaded groove after penetrating the slot 306, the outer surface of the top block 303 fitting against the inner wall of the connecting block 301, and an elastic structure formed between the top block 303 and the spring 302.

[0025] The overall effect of Embodiment 2 is that, during use, the two sets of springs 302 can act as shock absorbers. During tower crane hoisting, the main body of the wire rope 1 will experience instantaneous impact force due to material lifting, movement, or sudden braking. The main body of the chain 210, through the top rod 304 and the top block 303, also acts on the springs 302, allowing the springs 302 to absorb this energy through elastic deformation, preventing the impact force from being directly transmitted to the fixed frame 201 and the telescopic rod 207, thereby preventing structural damage due to stress concentration.

[0026] Working Principle: When adjusting the length of the fixed frame 201, the throttle 202 can be rotated via a threaded rotation to move both sets of telescopic rods 207 to the sides simultaneously, causing both sets of chain bodies 210 to expand outwards at the same time. The rigid structure of the chain body 210 can suppress the lateral sway of the wire rope, avoiding the problem of traditional adjustment methods affecting the stability of the anti-winding device in high-temperature environments. During use, the two sets of springs 302 can act as shock absorbers. During tower crane hoisting, the wire rope body 1 will generate instantaneous impact force due to material lifting, movement, or sudden braking. The springs 302 absorb this energy through elastic deformation, preventing the impact force from being directly transmitted to the fixed frame 201 and telescopic rods 207, thereby preventing structural damage due to stress concentration and significantly improving the structural reliability of the tower crane anti-winding device under dynamic loads.

[0027] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
